WILLIAM HENRY JOHNSTON, OF RALEIGH, NORTH CAROLINA.

PORTABLE FIREPLACE HEATING-STOVE.

Specification of Letters Patent.

Patented Apia13, 1920.

Application filed August 16, 1919. Serial No. 317,916.

To all whom it may concern.-

Be it known that I, WILLIAM H. OI IN- sToN, a citizen of the UnitedStates, residing at Raleigh, in the county of Wake and State of NorthCarolina, have invented certain new and useful Improvements in PortableFireplace Heating-Stoves; and I do hereby declare the following to be afull, clear, and exact description ofthe invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to stoves, and more particularly to portablehearth stoves, designed and adapted to be set in a chimney fire-placefor heating purposes.

The objects of the invention are to provide a simple, efficient andinexpensive portable heating stove which may be readily set up in afire-place for burning wood or similar fuel, and which is adapted to beeas ly removed and used in other fire-places of different sizes orwidths without requiring any alterations; also to provide a chimney fluestop or fireplace closing board for closing the chimney or draft fluetherein and forcing the hot air that rises from the stove lnto the roominstead of allowing it to escape up the flue, and which willautomaticallyadjust itself to the slant or angle of the sides of afire-place, which are slanting usually from front to back; also toprovide a forced down draft at the front of the stove for conducting theair downwardly to the fire in the fire box or chamber, and distributingthe air in such manner as to effect more complete combustion and preventwaste of the fuel and to increase the heat produced from a givenquantity of fuel, as compared with stoves heretofore ordinarily used infireplaces.

The invention will first be hereinafter more particularly described,with reference to the accompanying drawings, which form a part of thisspecification, and then pointed out in the claims at the end of thedescription.

In said drawings- Figure l is a front elevation of a portable stoveembodying my invention set in a fireplace ready for use;

Fig. 2 is a side elevation of the same arranged within or partly withinthe fire-place of the chimney, which is shown in vertical section Fig. 3is a top or plan view of the stove set in the fire-place, which is shownin cross section;

Fig. 4 is a vertical sectional elevation of the stove removed from thefire-place Fig. 5 is a cross section taken on the line 55 of Fig. 4;

Fig. 6 is a detail Vl8W of the flue stop detached and taken apart;

Fig. 7 is a detail fragmentary sectional view illustrating theconnection between the main portion and a side plate or adjustablemember of the flue stop; and

Fig. 8 is a detail sectional view taken on the line 8-8 of Fig. 1.

Referring to said drawings, in which the same reference letters are usedto denote corresponding parts in different views, the letter A denotesthe stove which may be constructed of sheet metal, or mainly of sheetmetal with cast metal parts and of oblong form with slightly roundedcorners as shown; one of the longer sides being the front. In said frontthere is a fuel door B, which is preferably hinged so as to opendownwardly, and a damper or draft regulating device C, and a cleanoutdoor D, the latter being preferably hinged to swing open sidewise.Between the draft device and cleanout door may be placed a foot-rail Eof any desired design. The stove is provided in its top with a draftopening and surrounding annular flange a, on or over which is fitted asmoke pipe F, for conduct ing the smoke and waste products of combustionup the chimney flue. The interior of the stove has a lining A of sheetmetal which extends around its sides and front and back, and at thefront this lining is set off or spaced from the inner side of the stoveso as to provide an air space which preferably extends entirely acrossthe front of the stove, below the fuel door, formin a forced down draft,which also serves to tribute the air along and over the fire, therebyeifecting complete combustion of the fuel and the consumption of moreair and less fuel than is usually required in fire-place stoves toproduce the same amount of heat. The letter G denotes a sheet metal fluestop or device for closing the chimney flue so as to force the heat thatrises from the stove into the room and keep the air in circulation. Theflue stop G has an opening v tening secured to the main body portion 7-therein through which the smoke pipe F passes, said smoke pipe beingmade to closely fit said opening so as not to interfere with the draftand being attached in a vertical or plate g, and side plates or wings gwhich are preferably tapering to conform to the slanting sides of thechimney or fire-place and are adjustably secured to said main portion,in telescopic fashion, by means of fasbolts which extend through the twoand through an elongated slot 9 in a connecting bar G to provide aslidable and pivotal connection and permit lateral adjustment. The bar Gis rigidly g by rivets or otherwise. In its original shape the flue stopis fiat but takes the curved shape shown in Figs. 2 and 4 when pressedinto the chimney or fire-place, as shown in Fig. 2. A springactuated'latch Gr is provided at the frontedge of the main portion 9 ofthe flue stop to take under the usual crossbar or supporting plate atthe front of the fire-place so as to hold the flue stop in properposition.

The letter H denotes an ornamental front or border, which extends acrossthe top of the stove and downwardly on each side to its bottom, so as toclose or cover the space at the front between the inner sides of thefire-place and the outer sides of the stove. It may however be dispensedwith. It is secured to the stove by bolts h passing through interiorlythreaded registering apertures in the margins of the upright portionsthereof and laterally projecting flanges or brackets 71. on oppositesides of the stove. As shown it consists simply of a sheet metal platehaving rows of diamond-shaped openings therein to give a neat andattractive appearance. When attached to the stove in the mannerindicated, it becomes a part thereof, and .is movable with the stove,but may be readily removed for the substitution of a similar front pieceoflarger or smaller size as desired for use in fire-places differing inwidth and height from the particular fire-place in which the'stove maybe set at the time.

The stove is designed to rest partly inside of the fire-place and partlyon the hearth, usually about one half or a little more than one halfbeing inside of the fire-place, although as shown more than one-half'isinside of the fire-place.

It will be understood of course that various changes may be made in thedetails and parts 9 and 9 arrangement of parts without departing fromthe spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A portable fire-place stove comprising a sheet metal body having afire box therein, a fuel door, a cleanout door, and an opening for asmoke pipe in its top, together with an air space extending across thefront of the stove, below said fuel door, and forming a forced downdraft, and a draft regulating device controlling the admission of airinto said space.

2. A portable fire-place stove comprising a sheet metal body having afire boxtherein,

a fuel door, a cleanout door, and an opening in its top for a smokepipe, together with an air space extendingacross the front of the stove,below said fuel door, and forming a forced down draft, a draftregulating device controlling the admission of air into said space, anda flue stop for closing the chimney above the stove structure.

3.
